Floods are one of nature's most (35) __________ natural disasters, affecting communities worldwide. They occur when an overflow of water submerges land that is usually dry. While the effects are clear, the causes can be varied. Understanding these hydrological forces is crucial for predicting and managing flood risks.

The most frequent cause is heavy rainfall. When too much rain falls too quickly, the ground cannot absorb it all, causing water to build up. In some cases, intense rainfall (36) __________ lead to flash floods, which are sudden and extremely dangerous, especially in hilly areas where water travels downhill rapidly.

In addition, floods are often caused by overflowing rivers. After heavy rain or snowmelt, river levels may rise significantly. When a river collects more water than its riverbanks can hold, it will flow over the surrounding land. (37) __________ is a common cause of flooding in low-lying areas near major river systems.

In today's digital age, the classroom is no longer confined to four walls. For teenagers in Vietnam and across the globe, learning support is often just a click away on platforms like YouTube and TikTok. Instead of just watching music videos or funny clips, students are increasingly turning to 'Edu-Tubers'—content creators who specialize in making education engaging. These creators produce tutorials on everything from complex math problems in the Ministry of Education and Training (MOET) curriculum to detailed analyses of Vietnamese literature, presenting a modern alternative to traditional study methods.

The primary appeal of this new educational landscape is its incredible accessibility. Unlike private tutoring, which can be expensive, or school lessons, which have fixed schedules, online content is usually free and available 24/7. An 'Edu-Tuber' can explain a difficult physics concept using vibrant animations, making it easier to understand than a static textbook diagram. This variety in teaching styles means students can find a creator whose method works best for them, offering a personalized learning experience that traditional schooling sometimes cannot provide.

However, this digital classroom is not without its risks. The biggest challenge is the lack of a formal quality control system. Anyone can post a video claiming to be an expert, which can lead to the spread of misinformation. Some creators might oversimplify complex topics to make their videos more entertaining and attract more views. They may prioritize engagement metrics over educational accuracy, potentially leaving students with an incomplete or even incorrect understanding of a subject. This places a significant responsibility on the student to be a discerning consumer.

So, how can students navigate this vast sea of information safely? The key is developing critical evaluation skills. Before trusting a channel, students should investigate the creator's credentials. Are they a teacher or a recognized expert in the field? Reading the comments section can also be insightful; other viewers might point out errors or offer different perspectives. Most importantly, information found online should always be cross-referenced with reliable sources, such as school textbooks or materials provided by teachers. This critical approach turns passive viewing into active learning.

Ultimately, social media platforms are unlikely to replace formal education, but they can serve as a powerful supplement. When used wisely, YouTube and TikTok can help clarify difficult topics, offer new perspectives, and make studying more enjoyable. The goal for modern students is not to avoid these platforms, but to learn how to use them critically and effectively, transforming their social media feed from a source of distraction into a valuable tool for academic success.
